The general case of selfadjoint elliptic problems is discussed. The author shows that if a suitable complementary variational principle is introduced, the differential problem coupled with a boundary integral equation can be reduced to find a stationary point of a constrained functional. Some numerical examples regarding the study of flows of ideal fluids past completely reflecting obstacles are reported and this is concerned with the numerical solution for a second order differential equation on unbounded domains mathematically.
